Filippo Palizzi Industrial Art Museum

Tucked away on the top floor of a school, this small museum is a hidden gem dedicated to Neapolitan ceramic art, showcasing works that trace the city's rich decorative craft tradition. Named after the 19th-century painter Filippo Palizzi, it has a quiet, forgotten charm that makes it feel like a genuine discovery. Fair warning though — it's notoriously difficult to catch open, so check ahead before making the trip.
